I've tried a Casio XJ-255. It has wireless and wired ethernet port. Unfortuantly, the ethernet port is only for changing settings. It looks like there is no way to share your screen over the network. The only wireless option is to connect directly to the unit but then you lose your connection to company network.

I need a projector that:

Can be hardwired to our network so our users can share their screen over LAN.

At the same time, it needs to be easy for guests to connect wirelessly directly to the unit so that they can use it without being on company network.

When I say at same time, I mean I don't want to have to reconfigure the projector every time we want to switch from a network user to a wireless guest ad-hoc user. It should support both connection methods without need reconfigure.

Also it needs wxga resolution. Sound over network would also be helpful.

Currently I'm looking at an Epson 915w. Even after reading all the documentation and calling epson sales, it's still unclear whether it meets our network requirements.

I really liked the Casio XJ-255. The features it had, worked very well and it was very easy to use. The problem is it doesn't work over the wired network.

The Epson 915w has the same resolution yet the picture is not as crisp. It does work over the network but sometimes there is a bit of lag once in awhile. It's still pretty good though. The software could be more user friendly. The wireless usb key it has seems pointless as it just installs the wireless connection software and uses your wifi card in your laptop.

I really wanted to keep the casio as I think it's more user friendly with the features it has plus the bulb last forever.

However, the colors were not an exact match as on the laptop. The Epson had colors that looked more identical the the lcd screens. Turns out that was very important to the marketing department so that's the one we had to go with. It will do everything I was looking for, I just wish the menus and software was a bit more polished plus the performance could be improved. The usb quick connect wireless key is not so quick. I think Casio's is quicker and more user friendly.

I believe the Black Box wireless VGA presentation system may be of interest to you. It allows you to wirelessly connect to any device that accepts a VGA input including projectors and LCD monitors. Check out the link below to view the video.

Thanks for the links but they are not what I'm after right now. If I was retro fitting an old projector, those would be fine. What I was after is a projector with my above requirements built in. If you look at this Epson 915w document http://www.epson.com/cmc_upload/pdf/brochure_technology.pdf , you'll see that it does everything, it just doesn't tell me if all the options can be enabled at once or if it has to be reconfigured to use the different connection methods.

The reason i'm suggesting using a streamer and an old projector (or any old projector) is due to the fact that you need WXGA resolution, Wireless AND Wired Networking.

Two of the three is no problem, all three is proving to be harder to find.

I've used InFocus projectors before, and while not top of the line, they are reliable.
